JetBlue Airways Corporation JBLU updated its guidance for the second quarter of 2021.The airline continues to expect flown capacity to decline approximately 15% in the second quarter from the comparable period in 2019, per a SEC filing. With air-travel demand still lagging the pre-pandemic levels, the company plans to keep managing capacity on a rolling basis to align its network with demand.With air-travel demand continually improving, especially on the leisure front, JetBlue has been witnessing improvement in bookings in recent weeks. Consequently, the carrier now anticipates revenues to decline 30-33% in the second quarter from the same period in 2019. This is narrower than the previously guided range of a decrease of 30-35%. The airline, however, gave a heads-up that it believes “demand and revenue recovery may be non-linear.”JetBlue Airways Corporation Price JetBlue Airways Corporation price | JetBlue Airways Corporation QuoteAdditionally, due to an uptick in fuel prices, JetBlue now estimates total operating expenses to decrease approximately 7% in the second quarter from the comparable period in 2019.
